This is a mixture of two or more miscible liquids.
The mixture is homogeneous only when these liquids are miscible.
Air, like other phases that contain only gas, is usually a homogeneous mixture. If the air contains solid particulates, such as soot, or liquid particulates, such as rain drops, the air is a heterogeneous mixture.
A homogeneous mixture is a mixture which contains only one pure element.
NH3 or ammonia is a compound. It is synthesized from H2 and N2. However, industrial NH3 product is a mixture because it contains not only NH3 but also other ingredients and impurities, that come during production phase.
A mixture which only contains substances which are in the same phases/state. eg, a gaseous mixture or a mixture of two aqueous solutions.

The act of mixing, or the state of being mixed; as, made by a mixture of ingredients., That which results from mixing different ingredients together; a compound; as, to drink a mixture of molasses and water; -- also, a medley., An ingredient entering into a mixed mass; an additional ingredient., A kind of liquid medicine made up of many ingredients; esp., as opposed to solution, a liquid preparation in which the solid ingredients are not completely dissolved., A mass of two or more ingredients, the particles of which are separable, independent, and uncompounded with each other, no matter how thoroughly and finely commingled; -- contrasted with a compound; thus, gunpowder is a mechanical mixture of carbon, sulphur, and niter., An organ stop, comprising from two to five ranges of pipes, used only in combination with the foundation and compound stops; -- called also furniture stop. It consists of high harmonics, or overtones, of the ground tone.
